NetBSD and OpenBSD share (at least try to) the wscons console driver
which has a notion of event which is not too far away from evdev. It
should be possible to write a more OS neutral event based input driver
which could cover all of Solaris, Linux and wscons events.

I must admit that I don't know too much about the current state of the
FreeBSD console driver though.
